A top ledge 28 ot the anvil 18 is of suiiicient length to overlie the tread 29 of the rail 11 when the end portion of the rail is positioned in the recess 26 as indicated partially by dotted lines in Figures 2 and 8 of the drawings.

A movable block or jaw 30 slides in side walls 31 between the motor support 19 and the anvil 18 having outwardly projecting ribs 32 slidable upon shoulders 33 in thc inner faces of the side walls 31, the jaw 30 having an upstanding rib 34 for limiting the movement of the jaw in closing upon the rail end by engaging the rib 34 with the ledge 28. Retaining plates 35 overlie the ribs 32 and are secured to the side walls 31 by screws 36 whereby the jaw 30 is removably positioned in the machine.

Two operating screws 37 are mounted through the frame 19 having their outer ends longitudinally slidable through perorations 38 in theadjacent end of the machine while the inner portions et the screws 37 are threaded for travel through openings 39 in the inner side of the frame 19. lThe inner ends of the screws 37 are swiveled as at 40 in the adjacent face of the jaw 30 whereby as will be evident, the simultaneous turning of the screws 37 will forcibly :teed the jaw 30 in either direction desired, toward or away from the anvil 18.

A power shaft 41 is journaled through the walls of the frame 19 longitudinally of the machine having a toothed portion 42 forming a long gear within the enclosure 43 of the Irame 19. Pinions 44 are secured thescrews 37 within the enclosure 43 in oonstant mesh with the gear portion 42 of the power shaft 41 while a large gear 45 upon the outer end of the shalt 41 is in constant mesh with a small pinion 46 carried by the drive shaft 47 of the motor 20.

ln this mannerfthe operation of the motor 2O controlled by such means as a rheostat 48 imparts great power to the shalt 41 and to the screws 37 permitting the screws to leed the jaw 30 in either direction desired by controlling the direction of the two-way motor 2O it being seen that the pinions 44 may slide longitudinally of the shalt 41 while being rotated through engagement with the gear portion 42 thereof. Rings 49 are preferably' carried by the shaft 41 at opposite'gides of the frame 19 preventing longitudinal movement of the shalt 41 during operation.

The form of scarf ends designed for forming on the rail 11 have been heretofore briefly noted it being also pointed out that the rail end or scarf joint section 59 ot the rail 11 has transverse periorations 51 therethrough adapted for receiving a locking bolt while a plurality of arcuate and tapered lugs 52 are formed upon the outer tace of the '14 in Fig. 3 of the drawings.

section 50 adapted for holding the head of the locking bolt against turning when the joint is assembled. The opposite scarf end 53 of the rail 11 has the outer face of its vweb 54 smooth for seating an expansion spring thereon, the web 54 of the end 53 as well as the web 55 of the end 50 being substantially as thick as the web 56 of the main body of the rail 11.

rThe inner face of the jaw 30 adjacent the anvil 18 is designed for receiving one of the die plates 13 or 14, the plate 13 being illustrated in use in Figs. 2 and 7 and the plate Suitable screws 57 removably secure the plates 13 and 14 to the forward face 58 o1 the jaw 30. Funch members 59 are carried by both of the plates 13 and 14 adapted 'for punching the perforations 51 through the scarf ends 50 and 53, outlet openings 60 being provided in the anvil 18 permitting the punched out portion of the rails to pass through the anvil t and drop beneath the table.

The rail 11 upon thestruts 12 as positioned from the rolls is received within the recess 26 or the anvils 13 of the two machines 10 which are moved longitudinally into position for so receiving the opposite ends 0I" the rails by pushing the machines 10 along the tracks 23. When the machines 10 are positioned for use as shown in Fig. 1 with the jaws 30 retracted as set forth in Fig. 6, the motor 2O is started in operation forcing the jaw 30 with its die plate either 13 or 14 into engagement with the end of the 1ail 11 which is positioned in the machine. r1`he plate 13 is provided with longitudinal ribs 60 as well as the punch members 59 and upon engaging the red-hot rail, the rail is forced into the recess 26 with the web in the recess portion 27 while the ribs 60 form the grooves 16 in the rail end 53 and the punches 59 form the peritorations 51 between said grooves. The material from the web which is punched out o1" the periorations 51 passes through the opening 60 and drops beneath the machine. ln a similar manner,

the die plate 14 in the machine 10 at the opposite end of the rail is provided with grooves 61 as well as the intervening punch members 59 which upon engaging the heated web of the rail end 50 produces the longitudinal ribs 15. The -.tace of the recess 26 of the anvil 18 in which the jaw 30 employs die plate 14 is provided with depressions 62 around the outlet passage 60 for producing the lugs 52 upon the rail web 55 as shown in ig. 3. At one stamping operation of the aw 307 the end of the rail that is positioned in the machine is quickly formed into the scart joint of the predetermined form. rlhe anvil face 55 is preferably inclined as at 63 adjacent the edge of such face where it is contacted by the web 56 of the rail 11 and each jaw 30 has an oppositely inclined 4portion ,64 whereby a thickened web portion 59 is providedat each end of the rail adjacent the scarf jointeither 50 or 53. In this mannerythe opposite ends of the rail llare formed as best shown in Figs. `9 to 14: both inclusive, the webs of therespective ends 50 and 53 being thickened for imparting greater strength tothe scarf joint when assembled. The motor 2O being of the `reversible type is operated for reversing the direction of rotation thereof when the rib 34 engages the ledge 28 with the device closed upon the work,` the reverse movement ofthe motor 2() retracting the j aw 30 and permitting the finished 4rail 1l to be removed for repeating the operation upon another rail.

The assembling oftwo rails in track formationis produced by overlapping the ends 5G and 53 of adjacentrails with the ribs l5 of the rail end 50 received in the groove 16 of the rail end 53. Spring locking bolts are then placed through the perforations 5l of the webs 54 and 55 with the heads of the bolts received between `the lugs 52 andthe springs at the opposite sides of the joint whereby a firm connection is established which will remain lockedduring all trafhc conditions although readily disassembled whenever the occasion requires. The construction of my machine is simple and carries out the object of forming rail ends in scarf arrangement as arcommercial proposition and thereby adding only slightly to the initial cost of a rail which greatly reduces the cost of the finished trackby eliminating the -fsh plates, lock nuts and the like. j
